Abstract: This invention relates to mountings for attaching an article to a generally cylindrical support, and in particular but not exclusively for a mounting to attach a bicycle lamp to a bicycle. The mounting 10 comprises an article support 11, an adjustable attachment member 12, a main body 13, a clamp member or strap 14, a bolt pad 15, a bolt 16 and a wing nut 17. The main body 13 and clamp strap 14 are held together by a bolt 16 which enables the clamp strap to be tightened so that a support can be trapped in a recess 24 in the main body 13. Couplings 34 and 37 are provided between the article support 11 and the main body 13 to provide rotational degrees of freedom about two orthogonal axis.
